Trengganu: 1921-41 Sultan $100 green & scarlet, top value. Postally superb U, on piece, tied by correct bilingual 'Trengganu' cds. SG 47 cat £11,000+ for loose used & such on piece should be worth +50% so £16,500+. Stunning example of this extremely rare top value, which seems greatly under-catalogued used vs mint as we could not find any other used examples offered anywhere in last 20 years! BPA photo-cert. (P)
